WESH 2 News is learning more about what led to a deadly police-involved shooting in Brevard County after officers said they were forced to fire. They said the man killed was angry about noise in the neighborhood.

The man who lived at the home was carrying a .45-caliber semi-automatic handgun, according to police, when he came out of his front door. Police also said he had an extra magazine full of ammunition.

"There will be no comment. I've said all I had to say," the girlfriend of the gunman told WESH 2 News.

The girlfriend of the 39-year-old man shot and killed by police in his front yard Tuesday morning was frustrated and had nothing to say to WESH 2 News hours after the standoff.

"Heard one gunshot and then came to the door and looked out the window. Saw all kinds of cops," said neighbor Kevin Bretz.

Palm Bay police said it started around 9:30 a.m. on Mariposa Drive when the man threatened to shoot three construction workers at his neighbor's house.

The neighbors told WESH 2 News they recently moved into their home and started fixing up the outside. The neighbors said it was a shock to them when the 39-year-old approached the home, visibly upset over the noise. They had never met the man.

"This is certainly something that we believe could have been prevented. We tried to get the guy out for almost an hour and a half, peacefully, so we could resolve it," said Palm Bay police Chief Mark Renkens.

Police said when the man eventually came out, he was holding a handgun and pointed it at police. Cpl. Jason McCoy fired one round from his department-issued rifle, according to police, fatally striking the man near his right ear.

"You just don't walk out to the police holding a gun," said neighbor Freen Manning.

Most neighbors, like Manning, who live across the street, said they didn't know much about the gunman, but WESH 2 found out he may have been an Army veteran. According to the 911 call, police said the caller believed he may have been under the influence.

"I'm just shocked," Manning said.

The Florida Department of Law Enforcement is investigating.

Palm Bay police said the 39-year-old had no prior run-ins with officers over the past two years. WESH 2 News is still working to find out the status of the corporal who shot the gunman.
